Abstract

For identifying plastics materials using a triboelectric identification system, a device 10 has detector heads 14, 16, 18. The, or at least one of the detector heads, has a surface 30 of a plastics material which can be rubbed against the sample. The plastics material surface is itself in contact with a support 34 of an electrically conducted material which does not come into direct contact with the sample surface. When the plastics surface of the detector head is rubbed against a sample, a charge is created on the conductive support which is measured to produce an output indicating the nature of the sample. <IMAGE>
